摘要:
试验研究证明：钾是盾叶薯蓣生长发育的重要营养元素之一，通过施用钾肥可显著增加盾叶薯蓣的产量和经济效益。在一定范围内施钾量与盾叶薯蓣产量和效益呈正相关，每1kg硫酸钾可增产15.64kg鲜蓣，新增纯收益28元。其中1 hm2配施225kg硫酸钾，平均1kg硫酸钾增产鲜蓣27.33kg，新增纯收益49.2元。在土壤速效钾含量为70～100mg/kg范围，1 hm2施用硫酸钾200～250kg可取得较好经济效益。
Abstract:
The experiment indicated that potassium is one of nutrient element for the growth of Dioscorea zingiberensis,through applying potassic fertilizer can increase the yield of Dioscorea zingiberensis and economic benefit.In certain scale,applying potassic fertilizer and its yield shows a positive relation,1 kg potassium sulphate can increase the fresh Dioscorea zingiberensis about 15.64 kg,the net benefit is 28 yuan.225 kg potassium sulphate is applied in 1 hm2,averagely 1 kg potassium sulphate can increase Dioscorea zingiberensis about 27.33 kg,the net benefit is 49.2 yuan.The available potassium is 70～100 mg/kg,applying potassium sulphate in 1 hm2 can achieve good economic benefit.
